There was a hint of relief and a lot of joy in Shosei Togo's voice after his best start of the season.

The Yomiuri Giants pitcher had just finished shutting out the DeNA BayStars by a razor-thin margin, and the cheers from the orange-clad fans who made up the majority of the 34,498 in attendance were easy to hear in the room behind the home dugout, where the right-hander finally had a chance to exhale.

Togo went the distance to protect the early one-run lead Kazuma Okamoto gave him with a home run, and the Giants earned a 1-0 victory over the BayStars at Tokyo Dome on Wednesday night.

"I was dealing with a lot of nerves from the very start," Togo said. "I'm tired, but I'm glad I got the complete-game victory."

Togo did not have much room for error, with Kenta Ishida having a solid night on the mound for the BayStars.

Okamoto, however, led off the second inning with a towering home run to left that held up as the difference on the scoreboard.

Okamot finished 1-for-2 with a pair of walks and has homered in three straight games. The Giants slugger is tied with DeNA teammates Toshiro Miyazaki and Shugo Maki for the Central League home run lead with nine.

”His batting has stood out recently,” Giants manager Tatsunori Hara said.

Okamoto homered in his final at-bat during Tuesday's game against DeNA and on the first pitch he saw on Wednesday.

"I went into the game in good shape," he said. "I hope I can hit another one tomorrow."

Okamoto is also on a four-game hitting streak, with at least one RBI in each.

"The pitchers are doing a great job, so we want to do whatever we can to back them up,” he said. “Togo helped us a lot today — it was nice pitching."

Togo struck out six and scattered five singles without walking a batter across a 127-pitch outing. He held Miyazaki, who began the night leading the CL in batting and tied for the lead in home runs, hitless in four at-bats.

He struck out Miyazaki in the ninth for the final out of his first shutout in front of the home fans at Tokyo Dome.

"I had good control with my forkball and my slider was also good," Togo said. "I'm glad I was able to finish it off."

Ishida (2-2) did his part to keep the game close. The Yokohama lefty allowed Okamoto's home run but otherwise limited the Giants to four singles and a double over seven frames while striking out seven in the loss. He allowed his only other baserunner on an intentional walk to Okomoto in the sixth.

The BayStars tried to answer after Okamoto broke the ice in the second. DeNA put runners second and third for Miyazaki with two outs in the top of the third, but Togo retired him on a grounder to third.

DeNA only had two runners reach base the rest of the way, with neither advancing past first.

Miyazaki finished 0-for-4 and has gone two straight games without getting on base after reaching in his first 34 games to start the season. He still leads the CL in batting by a wide margin even after his average dipped to .412.

The win was an important one for the third-place Giants, who have one more game against the second-place BayStars on Thursday before a three-game road series against the first-place Hanshin Tigers.

"We're going to take it one game at a time," Hara said. "We'll fight the way we always do."
